Cant say that I have.... the fellow you refer to just died a few weeks ago...
That was George Silver. He took over the ownership of Bergen Pianoforretning
before Nils, and worked as the tech in that store for 15 years or so before
that.

What I have noticed about Rippens through the years was the tendancy for
whatever that stuff they thought was glue to come loose..... leading to hammers
flying off their shanks in every direction after a few seasons.... then there
was that nasty metal cover for the pinblock... never could figure that one
out... here they wanted to make a cheap piano mind you.. and they go to the
trouble of making a tin covering that always came loose when they coulda just
glued some felt on top at a 10th of the cost... go figure.
